Oracle TimesTen In-Memory Database on Private Cloud Appliance and Compute Cloud at Customer

Oracle TimesTen In-Memory Database (TimesTen) is an in-memory relational database that can also be used as a cache. It delivers microsecond response and high throughput for OLTP applications. TimesTen supports SQL, standard APIs, complete ACID properties, and highly available replication mechanisms. TimesTen powers mission-critical applications across industries including telecom, e-commerce, and financial services.

TimesTen?offers unrivaled performance, simple installation and management, high performance, and high availability. It is well suited to running in containerized environments and, combined with the TimesTen Kubernetes Operator, provides a simple and robust solution for high-performance, highly available data management in Kubernetes environments.

Oracle Compute Cloud@Customer is a fully managed, rack-scale distributed cloud platform that lets you use Oracle Cloud Infrastructure (OCI) computing, storage, and networking infrastructure services anywhere. It allows you to gain the benefits of cloud automation and economics while addressing data residency requirements by controlling the location of your data and its processing—all remotely managed by Oracle. The Container Engine for Kubernetes (OKE) is a scalable, highly available service that can be used to deploy any containerized application to Compute Cloud@Customer.

Oracle’s Private Cloud Appliance (PCA) is a rack-scale engineered system that delivers Oracle Cloud Infrastructure (OCI) compute, storage, and networking constructs on-premises. It is architected to provide a highly resilient, modern application environment. It is an ideal platform alongside Oracle Exadata and Oracle Database Appliance platforms, offering the lowest latency and highest performance between the application and database layers. Private Cloud Appliance is designed for customers who want a cloud-like development and deployment experience while also meeting data residency requirements. Oracle Private Cloud Appliance Container Engine for Kubernetes (OKE) is a scalable, highly available service for deploying any containerized application to the cloud.

TimesTen In-Memory Database for Kubernetes provides the following benefits:

• Extreme OLTP performance: Achieves extremely low latency application performance by delivering data from an in-memory database that is colocated with applications.
• Easy installation and deployment: Includes Helm charts and YAML manifest files that make it easy to install and deploy TimesTen databases.
• Automatic monitoring and management: Supports automatic lifecycle management of TimesTen databases, including taking auto-corrective actions. Automatic management reduces the need for human-assisted database maintenance, allowing TimesTen production deployments to run more efficiently.
• Highly-available data management: Uses active standby replication topology to support high availability

A TimesTen database resides entirely in physical memory and is persistent and recoverable. You have the following options

• Oracle TimesTen In-Memory Database in classic mode (TimesTen Classic) is a memory-optimized relational database that provides applications with responsiveness and high throughput. Through transactional replication, TimesTen offers high availability for the in-memory database.
• Oracle TimesTen In-Memory Database Cache is ideal for caching performance-critical subsets of an Oracle database for improved response time in the application tier. Cache tables can be read-only or updatable. Applications automatically read and update the cache tables using standard SQL, and data synchronization between the cache and the Oracle database. Cache offers applications the full generality and functionality of a relational database, the transparent maintenance of cache consistency with the Oracle database, and the high performance of an in-memory database.

Usage instructions

See Container Engine for Kubernetes on Compute Cloud@Customer, Oracle Private Cloud Appliance - Container Engine for Kubernetes and Deploy TimesTen database with TimesTen Kubernetes Operator for details about how to:

• Create an OKE Cluster on your Compute Cloud@Customer or your PCA
• Log in to Container Registry on your development host and create a Kubernetes Secret to store the credentials for your Kubernetes cluster to access the container image from Container Registry.
• Deploy the TimesTen Operator and create TimesTen databases using either YAML manifest files or Helm charts.
